SOIL-CULTIVATOR.

To all whom t may concern: y

Be it known that we, Marr Simon, a citizen of the United States, and Euro HOG- LUNDTa citizen of Russia, both residing at Duluthrin `the countyof St. Louis and State of Minnesota, have invented certain tical and simple` means for conveniently lowering and raising the soil cultivating elements `to and from engagement with the soil, both for regulating the depth of cultivation and for transporting the machine when not in operative action. i

Other objects andadvantages of thenovel combination of elements will appear in th further description of the device.

In the accompanying drawings forming part of this application and in lwhich like reference ycharacters indicate like `parts;- 1Figure 1 is a top plan view of the completely assembled machine as it would appearin action. Y

Fig.f2 is a side elevation of same except that theY soil cultivating elements are illustrated as being raised and the near wheel and part of the frame are broken away for comprehensive illustration ofthe raising and lowering mechanism.

Fig. 3 is a side elevation of a fragmental portion of the frame where connected to the axle. `The device comprises a two wheeled vehicle having a single axle 1 square incross section throughout except at the extreme ends where the wheels 2-2 are rotatably .mounted thereupon.

l A frame` preferably made of flat bar iron comprising the sides 3-*3, rear portions ll-l, front 4portions-- and central member 6 is suspended from the axle and rotatably carries therein the soil cultivating elements, 7 u The sides 3-3 of the frame are attached Speccation `of Letters Patent.

Application led April 2, 1917. Serial No. 159,229.

to the axle adjacent the wheels 2 by straps 8 which overlap the axle and are securely attached by bolts or rivets 9 to the sides 3, there being onestrap` upon each side. The central member 6 is also' attached to the axle 1 in a like manner by the strap 19.

` The various portions of the frame are securely riveted together to form a rigid support for the cultivator-shafts 10-10 and which frame is preferably slightly V shaped with the apex thereof extending away from the axle 1. Each shaft 10, being parallel with the sides of the half of the frame in which it is mounted, fixes said shafts at an angle to the axle andwhich angle is that determined by practice to be the most practical for the desiredresults in cultivation.

The shafts 10--10 are square in cross section throughout except at their extreme ends where they are journaled in suitable outer boxes, 11-117 and the central double bearing ,box 12, which accommodates the inner ends of both the shafts. these boxes being `of the cultivating blades. This method, however, of mounting cultivator blades is old and forms no part of my present invention.

Between each pair of cultivating elements 7 and passing beneath the sleeves between the elements, is fixed a bar lil, which may be either square or round, and fastened at one end to the rear 4 of the frame and at the opposite end to the front 5. These bars are for the purpose of strengthening the frame and acting as cleaning guards to the cultivating elements to .prevent the latter carrying sods or other loose material about with them as they rotate. A

The sides 3 of the shaft supporting frame are bentboth vertically andlaterally at a point opposite the peripheral edge of the wheels so that they flare outwardly beyond a plane with the inner side of the wheels and extend upwardly at an angle to that portion connected with the axle, which brings the rear portion of the frame substantially parallel with the surface of the ground `when the cultivating elements are in service.

'bifurcated portion.

The central member 6 is also bent upwardly to coincide with the side members. Adjacent and just forward of the angle in each side and central member is fixed a downwardly inclined brace 15, the free ends of which upon the side members, are each attached as at 1G to the end of a depending arm 17. The upper ends of the arms 17 are enlarged and. have a square hole ytherethrough which completely surrounds the axle l and are clearly seen on Fig. 1.`

The brace on the central member 6 is similarly connected intermediate depending arms 18-18 identical with the "arms 17, except that there are two of them and spaced apart to permit of the strap 19 being established therebetween. This Spreading yof the arms 18-18 also permits of the pivotal attjafchment of the tongue supporting member 2() therebetween and upon the same pivotal pin which is designated at 21.

l' The end of the member 20, Vthroirgh which the pin 21 passes, is bifurcated to permit of thefree end of the cooperating bracel 15 to also surround the pin intermediate said Thus the frame, which suports the'c'ulti vating' elements, is securely non-rotatably lixed to the axle and braced upwardly at the 'sides and center from fixed arms depending from the axle. 'p

The tongue supporting meinber`120, which also supports the drivers seat and the lever controlling mechanism, is, as before stated, pivot'ally supported upon'the pin 21 and one edge thereof as indicated at 23, is tnrned upwardly at right angles to the body portion to strengthen same 'and to forma suitable support for the lever 241, which is pivoted thereto at 25. This upturned'p'ortion 23` also vsupports the lever engaged quadrant 26. f

The lever 24 has formed integral therejvith the depending backwardly curved extension 27, the free end of which is pivotally `attached at 28 to the `link 29,the 'opposite end of which latter is pivotally attached 30 to the'free end of the arm 31.

` The arm 31 is identical with the arms 17 and 1S and is mounted upon the axle in the same non-rotatable manner in respectl to the axle, 'except that'it is disposed at right anglesthereto and extends forwardly instead y of downwardly;

rant

Notches 32 are formed in the peripheral edge of the quadrant 2G and into which any supporting member, may be readily changed by the "operator 'as is obvious.

A yoke, comprising the vstraight trans verse portion 34 and two inclined inwardly bent 'side portions 35u35, is attached as at 86 to the forward end of the tongue supporting member 2O and the two free ends pivotally `mounted upon lthe pins 16 carried by the arms 17, one upon each side of the machine, thus forming a substantial lateral brace.for the member 2O and which is free tobe raised and lowered with themember 2O in respect to the axle 1. i

` Depending from the member 2O and approximately midway of its ends, is a strap 37 to receive the end of the tongue 38, and another somewhat larger strap 39, for alike purpose', depending fromthe junction of the member 20 andthe yoke. f

A suitable seat 40 is yieldably supported from the member 20, asV is customary in similarly constructed machines.

In operation, thetongue being supported the horses hitched thereto, that" portion of the machine directlyattaclied to theton'gue l will remain substantially stationary, and the axle 1, together with the culti-'vater carrying frame fixed thereto, will .have itsV pivotal bearing inthe; wheels 2 2, the connection with the-tongue frame also being `pivotal as f When the lever 24 is drawn toward `the loperator in the seat 210,- the arm 31 will be 95 drawn l downward, which action 'will roel; the axle 1 in the` wheel 2```2 and thus tip upw'a-rdly the frame with the cultivato'rs thereinas illustrated in Fig.2. lVhen the lever 24; is thrown forward, the cultivators will be brought in contact with the ground for actioinand the depth of whichin relation to the ground may be regulated bythe lever 24.

Itis evidentfth'at tliekmachine may be made larger and a greater number of sets of cultivating elements used if desired," The c'ultivators proper may be as shown orjeither ters Patent is 1. A cultivatorofthefclass described, comprising in combination a single two-wheeled axle, a vcultivator carrying frame rigidly fixed to and' extending rearwardly 'from said axle,`t`he outermost portion of `said-fr'nn'e being bent upwardly forming anobtuse angle therein, a plurality of depending arms fixed to the axle, a second frameextending forwar'dly of said axle and pivctally carried in the free ends of the arms, bracesextending from the angle in the c'ultiva'tor frame to the free ends of the arms, an arm 4centrally located upon the axle and extending forwardly at right angles to the first ment-ioned"arms.

and an operating lever pvotally mounted upon the second frame and Connected with the last mentioned arm whereby the culti- Vator frame is raised or lowered by the rocking of the axle.

2. The combination with a oultivator of the class described, having a eultivator earrying frame rigidly fixed to the Vehicle axle, of a second tongue supporting frame pivotally suspended a fixed distance below the axle independently of the rst mentioned frame and normally substantially parallel nesses.
